LMO Flashcards
LMO definition?

CAT I company limit
200ft/550m RVR
CAT II company limit
100ft/350m RVR
CAT IIIA company limit
50ft/200m RVR
CAT IIIB company limit
0ft/100m RVR
Below what minima are low visibility taxi routes issued for?
1200ft/550m RVR
How long can it take airports to get ready for low visibility operations?
30min
Are there visibility limits for taxi?
No
Should you cross a lit stop bar when you are cleared to cross?
No
If unsure of position what should you do?
Stop and advise ATC
When must a low visibility take off be done?
When visibility less than 800m or RVR less than 550m
Do LVPs need to be in force for a low visibility take off?
Yes
Low visibility take off runway length requirement?
Full length
Crosswind limit for low visibility take off?
15kts
Difference between faile passiv and fail operational?
Passive = in event of failure no significant deviation of aeroplane flight path or attitude Operational = Capable of Autoland following failure of any single system component after passing alert height
Alert height definition?
Height above runway which a CATIIIB must be discontinued if a specific failure occurs
Air NZ alert height?
100ft RA
Autoland is not recommended on runways with braking action worse than?
Medium
What low minima approaches are limited to for contaminated runways?
CATII or CAT IIIA (no CAT IIIB)
Wind limits for Low Minima Landing:
- Headwind
- Tailwind
- Crosswind (Dry, wet, contaminated, Austrlalia with RVR <200M)
- Headwind = 25kts
- Tailwind = 15kts
- Dry crosswind = 15kts
- Wet crosswind = 15kts
- Contaminated runway = 10 kts crosswind
- Aus RVR <200m = 10kts
CAT II min visual cues?
Minimum 3 rows of axial lights
CAT IIIA min visual cues?
Visually confirm tracking within runway confines
Typically, what visual references are needed for CAT II?
- A segment of the approach lighting system
- The runway
- The touchdown zone
- Typically, 3 rows of approach lighting system
Typically, what visual references are needed for CAT IIIA?
- Visual references sufficient to confirm the aircraft is over the touchdown zone (mandatory go around if not)
